So, I replaced the radiator and I forgot to clamp down one of the hoses and it leaked out and the engine overheated. Now I have a knocking noise and it bogs down at 2,000 RPMs.

Hi,

Other than a knock and power loss, are there any other issues? For example, are there any indications of coolant mixing with the engine oil? Coolant usage? White smoke from the exhaust?

Also, could you record the sound you hear and upload it for me to hear?

In the interim, here are two links I would like you to look through. One is related to engine noises and the other to head gasket symptoms. See if anything mirrors what you are experiencing.

Let me know.
